内容記述 | Two types of noise recorded in seismic explosion experiments around Syowa Station in Antarctica are discussed. One is wind-induced noise which is detected directly by a seismometer. This type of noise increases with a wind velocity, and when the wind velocity is over 15 m/s, seismic observations are not in success. With the object of noise reduction, seismometers buried in a hole at depths of 3, 5 and 10 m were examined, but the noise existed at 10 m. Seismometers should be buried deeper than 10 m. Another is electrostatic noise which frequently deranges a clock signal or destroys an electric circuit in the worst case. This noise is caused by drifting electrified snow, not by a seismometer itself. It was excited on a signal cable stretched on the snow surface from the seismometer to a recorder. To reduce this noise, the cable should be as short as possible and be laid in parallel with the direction of wind. | |||||||||
